Relution behind firewall/proxy

Hello, i’m curious if anyone has successfully installed and/or used Relution behind the firewall. I see the documentation specified it must be exposed directly to the internet and cannot run behind a proxy.

my UCS server will never be directly exposed to the internet, but I can set up routes and firewall between for the specific ports.

Thanks, I don’t want to spend a ton of time learning how to use it if I won’t be able too.
